Kaluza-Klein-Jordan-Brans-Dicke理论中的准Torsion场及其在宇宙论中的简单解

The Quasi-Torsion in Kaluza-Klein-Jordan-Brans-Dicke Theory and Its Simple Solution in Cosmology

从高维时空的几何度规出发,讨论了推广的 Kaluza-Klein 型 Jordan-Brans-Dicke 理论,指出存在一种与标量场φ的时空梯度有关的准 Torsion 场.并给出了宇宙论中的简单解.

This paper discusses the KKJBD theory from a higher dimensionalgeometric standard,and points out that the quasi-torsion relates to thespace-time derivatives of the scalar field φ,resulting in a simple solutionin Robertson-Walker cosmology.
